To all whom it may concern/.- 1

Be it known that I, HOWARD E. HARBAUGH,

a citizen of the United States, residing in the city and county of Kenosha, in the State of Visconsin, have invented certain new and useful Improvements in Knitting-Machines, of which the following is a specification.

' 482,173, granted to myself September 6, '1892;

and it consists of certain new and useful fea tures of construction and combinations of parts hereinafter fully described, and specifically pointed out in the claims.

Referring to the accompanying drawings, which form apart of. this specification, Fig ure 1 is one side of a vertical section of a knitting-machine, containing my improvements. Figs. 2 to 5, inclusive, are views of detailed parts shown in operative relation and connection in Fig. 1.

Fig. 6 is an interior view of the operative parts of the cam-cylinder of the'machine. Fig. 7 is a view of the head of the machine minus its interior parts. Fig. 8 is a bottom plan view of the sinker-slide cam-ring. Fig. 9 is a top plan view of a fragment of the same.

Like letters of reference indicate corresponding parts throughout the several views.

A is a needle-cylinder having a series of vertical radial grooves A therein corresponding with the number of needles in the machine and provided with a horizontal annular bearing A and a circular horizontalsinkerslide bed and sinker cam-ring bearing A which is supported by. a part G, to be described hereinafter, and prevented from turning on said needle-cylinder by means of a setscrew A.

C are needle-elevating cams which are supported by and are freely rotatable on the bearing A which is driven upon andthereby rigidly connected with the needle-cylinder A.

D is a needle, the shank D whereof terminates in a hook D E is a needle-slide having aimatrix E'thereinthe counterpart of the hook D on the shank of the needle D, which it receives- 1 i and provided witha lug E a stop E an in clined friction-stop E adjacent to. the stop E and a needle-bearing E the functions whereof will be fully explained hereinafter.

The construction of the hook D the matrix E, and the bearing E so locks the hook into the matrix that the needle D has rigid connection with' the" needle-slide E when I pressed toward the outer edge thereofthat" is, toward the part G.

F is a combined presser and stop having a bearing F on the part .G, resting on the needle-cylinder A, and to be described hereinafter, whereon it may be oscillated.

F is a spring normally impellmg the com-i 'bined presser and stop F into engagement with the stop E and adjacent friction-stop E G is an annular support for the combined.-

presser and stop F and its spring F The support G rests on the annular projection G on the needle-cylinder A, and has a series of vertical grooves G therein corresponding in number and coinciding with the needle-slide grooves A in the needle-cylinder A.

G is a ring for securing the springs in the slots G in the annular support G. The

springs F are not attached to any of the parts composing the machine, but are simply held loosely in the slots G by means of the ring (3.

' l is a cam-oylinder, having a stop-cam H, rigidly connected therewith. The stop-cam 11, while compelling the needle elevating cams C to rotate synchronously with the camcylinder H, allows them to travel up and down with the needle-cylinder A, as indicated by dotted lines in Fig. 6. The object of the construction-just described is to cause the stop E on the needle-slideE totravel up ward into engagement with the combined presser.

and sto F at ever rcvolution of the cain- ..)ki 1 ring.- H

Il is a standard for supporting. the :yarncarrier and otherparts of the -.machin e;

l is a sinker can1 -ring, having a sinker-slide groove 1' thereimjand provided with sinkerslide cams l ypivnted thereto at I.

I are springs normally impelling the sinkerslides 1 through the sinker-slide earns 1 against the work-in the machine.

.5 .areadjustabi'e projections, screws being shown, one of which the standard 11 always armed bracket K one of said slots K only being shown, Fig. 7.

L is a needle-latch-controlling ring-seg ment resting rotatably on the sinker can1- "ring I, the ends whereof are provided with opposite inclines L.

L are screws inserted through the slots K in the braeketK and set into the ring-segment L, which construction permits the ringsegment L to be freely raised and loweredand still requires it to rotate synchronously with the standard H. I

M is a yarn-carrier, from which project needle-latch openers M integral or rigidly 1 connected therewith.

M are ways, formed by the opposite inclines L on the ring-segment I and the counterpart opposite inclines M on the lower edges of the needle-latch openers l\ N is aslide for maintaining the needle D in action.

Fig. 1 represents the parts of the machine in proper position to knit around and around to form the legs and feet of stockings. As the machine starts in to knit theheel or toe of a stgcking, the slides N descend out of engagement with the needle-slides E. The springs F operating through the combined pressers and stops F, will throw the lower end of the needle-slides E over to O and about half of the needles D of the machine will go out of 1 action, and while these needles remain out of action the inclined friction-stops E will rest upon the corresponding inclined adjacent surfaces lon the combined pressers and stops F, and thereby maintain said needles, through their slides E, suspended until they again gointo action. Obviously the stops E will pre- "ent the'needles D from traveling anyfarther upward in the machine than indicated in Fi 1.

lhe ring-segment L prevents the latches of the needles D from closing when the machine is knitting and the needles are in the position shown in Fig. 1, which is the highest point C, resting on the bearing A rigidly connected with the needle-cylinder A, the'sinkcr camring I, and the ring-segment L participate. The slot-andscrew connection between the ring-segment L and bracket K permits the yarn-carrier M to always remainat the same elevation.

I claim- 1. In a knitting-machine, in combination, aneedle having a shank terminating in a hook, and a needle-slide, furnished with a needlebearing, on its inner edge, and provided with a matrix, the counterpart of the hook on the needle-shank, said needle-bearin g and matrix affording provision for locking said hook into the needle-slide, substantially as and for the purpose specified.

2. In a knitting-machine, in combination, a needle cylinder or bed, a needle-slide provided with a lug, a stop, and an inclined adjacent friction-stop, and a combined oscillatin g presser and stop having a bearing on said needle cylinder or bed and engaging the stops on the needle-slide, anda sprin g normally impelling the combined oscillatory presser and stop into engagement with the stops 011 the needle-slide, substantially as and for the purpose specified.

' 3. In a knitting-machine, in combination, the cam-cylinder, the needle-slides, the combined pressers and stops and their actuatingsprings, the needles, the needle-elevating cams vertically movable in the cam-cylinder, and the needle-cylinder provided with a horizontal bearing for supporting and elevating said cams and needles, substantially as and for the purpose specified.

l. in a ki'iitting-machine, in combination, the needles, a needle-cylinder, a ne'edle-latchcontrolling ring-segment, the ends whereof are provided with opposite inclines, the combined yarn-carrier and needle-latch openers located between the inclined ends'of the ringsegment and forming with them ways down of said bracket, substantially as and for the purpose specified.

, HOWARD HARBAUGII.
